Step 1: Make a Fire

this is because the back of a can is a perfect parabola, that means you can focus light with it!

piece of paper
sunny day

rub the chocolate over the bottom of the can until it reflects good

step 2. go outside and focus the sun with it on your piece of paper

step 3.
have fun

Step 2: Popcorn Machine

what you need:
tape
tealight
nails
can
vegetable oil
corn
knife

step 1
make the can; draw a triangle on the can like in the picture and cut it out like I did

step 2
make the holder. get the tealight and tape the 4 nails around it

step 3
put the mixture in. 2 teaspoons of corn and 1 teaspoon of oil

step 4
the rig; put the can on top of your nails

step 5
the popcorn; light wait add salt and enjoy!

    bb guns and airsoft are about the same if you shoot someone with a gas airsoft gun it has about the same power as a bb gun

    airsoft guns shoot plastic bbs. and BB guns shoot metal ones but if you have a air cannon you cann shoot any thing you want, like a stapler, cellphone, or a jackknife.

    There's no way that this Instructible legitimately got something like 46 votes. There's only eight comments and less than 500 views. This can't be right. Not bashing the author here, I'm just confused...

    Right now, nowhere. To prevent people from trying to skew the top votes list with fake votes, we've hidden it away. We'd prefer that people focus on the quality of each instructable than if people are cheating.
